Discover 10 Trustworthy JavaScript Test Tools (From AVA to QUnit)

No doubt, JavaScript code testing is crucial to ensure that applications are running seamlessly on Node.js or in the browser. It is also important for keeping the bugs out. There are various options for JavaScript testing that are open to the developers. Moreover, there are framework and test runners for unit testing, functional testing, and integration testing. All these are available for the JavaScript ecosystem, offering coverage for both browsers and Node.js, including React and Angular frameworks. In this blog article, we will cover ten of the most trustworthy JavaScript test tools that the developers can use in their apps.

1. AVA

This is a test runner designed for Node.js. It offers precise API, process isolation, comprehensive error output, and support for new language attributes. It is perfect for testing server applications and, of course, Node.js models. However, it is not the perfect option for testing UI applications. AVA also offers a unique feature that indicates a test as ‘to do’ task. It is essential to mention that each file is tested and ran separately. Additionally, it has some other benefits, which include speed and minimalism, the capability to run tests in tandem, and straightforward test syntax. It also supports sync functions along with observables.

2. Cucumber.js

Cucumber.js is another test tool for JavaScript implementation. It runs on managed Node.js editions and in contemporary browsers for the web. The Cucumber tool has a number of benefits, which include the ability to carry out automated tests written in a simple language to be readable for the whole team. It also enhances team communication, collaboration, and trust. Cucumber.js entails an implementable file that can be used to run your test features, also known as suites.

3. Enzymes

This is also a testing tool designed for the React JavaScript UI library. Enzymes is designed to make testing React components pretty simple and clear. It is easy for the developers to manipulate, simulate, and traverse run-time based on the output. Basically, its API imitates jQuery API for DOM manipulation as well as traversal. It is essential to mention that Enzyme is not restrictive of an assertion library or a test runner. It can also be used to evaluate the React Native components.

4. Karma

This test runner allows the execution of code on multiple web browsers. As a matter of fact, Karma supports every major browser, including mobile versions. According to the developers of this project, Karma offers the perfect setting where the specialists are not required to set up huge loads of configurations. Rather, they can just write code and receive immediate feedback on their tests. Karma is the perfect choice for a low level of unit testing.

5. Jasmine

This tool is regarded as a ‘behavior-driven’ testing framework. It doesn’t depend on any other JavaScript frameworks and doesn’t require a DOM. Its advocates allude to its syntax as being capable of engendering seamless writing for tests. Jasmine is managed by Pivotal Labs and it is ideal for websites testing, Node.js, and any other thing that uses JavaScript. It is designed to enable ease of testing on a wide range of browsers and use cases. It is important to mention that Jasmine strives to be minimally dependent on others, remaining small and manageable.

6. Jest

Jest is believed to be an extensive JavaScript testing tool that functions innovatively and requires no configuration. It is designed for most of JavaScript projects. On Jest, tests possess special global state, which can be run concurrently. Initial failed tests should be the first to be run and the runs need to be readjusted based on the extent of test files. It works with renowned JavaScript technologies, such as Babel, React, Node.js, Vue, and Angular. The tests can be run in order to put the bigger objects in a good perspective. When it comes to testing files, Jest incorporates objects and methods into a global setting, without having to import them.

7. Luna

This is an opinionated testing framework that needs no configuration, and according to the product information, the developers can test run their first unit within a couple of minutes. With Luna, there is no need for installing any other modules to produce code coverage details. The tests should be written in ES6 modules and run in a browser automatically. This tool supports concurrency, which means the test groups can be run simultaneously. It doesn’t allow trans-piling, and this means it won’t work with TypeScript or CoffeeScript. It’s essential to mention that Luna doesn’t support older browsers.

8. Mocha

Mocha is a test framework that functions on Node.js along with in the browser. It makes asynchronous code testing fun and simple. With this tool, the developers can run tests serially, and according to the advocates of the tool, it provides flexible and accurate reporting and helps map out unaccounted exceptions for accurate test scenarios. The professionals can choose the Wallaby.js tool for continuous testing. This allows you to cover the real-time code with Mocha and any other assertion library. Suffice to mention that it incorporates application frameworks like through Konacha, and enables the developers utilize Mocha to evaluate JavaScript in Ruby while using Rails applications.

9. Protractor

This is a nonstop testing framework designed for Angular and AngularJS. Here, testing is done against the application in a browser, and it interacts with the applications in the same way as the users usually do. It has an automatic waiting ability that allows it to carry out the next step of a test as soon as the webpage is done with the pending tests. It is essential to mention that Protractor was developed on WebdriverJS.

10. QUnit

This is also a JavaScript unit testing framework used by jQuery, jQuery Mobile, and jQuery UI projects. It was originally created as an aspect of jQuery and it is believed to be easy and fast to use. QUnit has an opinionated but extensible and lean API, which can be utilized to evaluate almost any basic JavaScript code. The tool offers immediate feedback when there is a failed assertion or test with adequate information to help the developers understand what the issue is.

Conclusion

Each of the above-mentioned JavaScript tools is reliable and worth using. Think carefully and make your decision on which one or how much you need to obtain. All of them are able to help you in your doings in a quality manner.
